@juancarlospaco this is easily done on your own system, not in a PKGBUILD, given that building packages runs as root:

sudo groupadd unrealengine-users
sudo usermod -aG unrealengine-users (your-username)
sudo chown -R root:unrealengine-users /opt/unreal-engine
sudo chmod -R 775 /opt/unreal-engine

Permission issues like this are already mentioned on the UE Arch wiki page: https://wiki.archlinux.org/title/Unreal_Engine_4#Installing_from_the_AUR

This is a user system problem; I already did what I could without needing users to do the above by giving the 777 permissions. If it still gives you trouble, you'll have to use the example to solve it or change the install location to somewhere you have user permissions by default (as I cannot do this for you).

Will update to 5.0 when it is released.

@Neko-san Yes, thanks, I read and executed the groupadd/usermod/chown/chmod, but still that not fixes it, do it on your PC, open UE5 in the create new project window, try to create a new project but using "C++" instead of "Blueprints" and you likely will see errors.

@juancarlospaco This isn't the first time I've answered that question for you; I even pinned it:

If you try to create a pure C++ project (No Blueprints) it complains:

An error occurred while trying to generate project files.
Running /opt/unreal-engine/Engine/Build/BatchFiles/Linux/Build.sh  -projectfiles -project="/home/juan/ue/CPPero/CPPero.uproject" -game -engine -progress
Setting up bundled DotNet SDK
chmod: changing permissions of '/opt/unreal-engine/Engine/Build/BatchFiles/Linux/../../../Binaries/ThirdParty/DotNet/6.0.302/linux/dotnet': Operation not permitted.

I fixed it by executing:

sudo chown $USER /opt/unreal-engine/Engine/Build/BatchFiles/Linux/../../../Binaries/ThirdParty/DotNet/6.0.302/linux/dotnet

It is Ok to chown or chmod because its a local bundled copy (it is a weird path but works), this should be added to the install process IMHO.

@OdinVex I'm out of town right now, so I can't do anything about that until Tuesday

OdinVex commented on 2023-09-02 18:08 (UTC)

@Neko-san Fire has changed the repository URL to fire-archive/QtCreatorSourceCodeAccess. If you use https you can avoid users being asked for their SSH key password a second time (if they use one).

did anyone here launch this on Intel's iGPU yet? I really want to develop with unreal, but the engine crashes on VK_ERROR_OUT_OF_DEVICE_MEMORY: https://paste.opensuse.org/pastes/d1823ae21057

Neko-san commented on 2023-08-27 19:43 (UTC)

Added them to optdepends because it's not strictly required for UE5 to be built nor actually function

juancarlospaco commented on 2023-08-27 19:29 (UTC)

Add to dependencies fake-ms-fonts or ttf-ms-fonts because demo/free/sample/example/tutorial contents often use it.

@Neko-san While your pinned method of setting permissions will technically work, it will break pacman permissions. (In my opinion,) a more preferred method would be to set an access control list to let members of the newly created group write into the unreal-engine folder. Just like how you setup Android Studio on Arch Linux. (https://wiki.archlinux.org/title/Android#Making_/opt/android-sdk_group-writeable)

# groupadd unreal-engine
# gpasswd -a <user> unreal-engine
# setfacl -R -m g:unreal-engine:rwx /opt/unreal-engine
# setfacl -d -m g:unreal-engine:rwX /opt/unreal-engine

This will maintain root:root disk permissions, thus matching the permissions in the package file and making pacman happy, while also giving the group unreal-engine rwx access to /opt/unreal-engine. But hey, you know, that's just like uh, my opinion, man.
